First map of 2020 ! Congratulation on the realease.
It's really good that it's not a box map. I just try it and for a first map it's not that bad. Unfortunately a lot of rooms are empty and useless and it gets boring really quickly, but i'm sure it can get fun on multiplayer. Also i like the fact that the dogs are custom and you didn't neglected the outside of the map and that's a good point. So keep having fun making map !
For the issues : The first dog round is glitchy they didn't spawn at all and I didn't get the max ammo. Some zombies get stuck behind the barricades and don't get out. You can also exit most of the zombies barricades as you can see on my video, and that's all !
